VICTOR NATALE, OF NEW YORK, N. Y.

ICE-CBUSHEB.

Application filed June 18,

To all whom it may concern:

Be it known that I, VICTOR NATALE, a citizen of the United'States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Ice-Crushers, of which the followin is a specification.

This invention relates to devices for crushing ice on city streets and the principal object is to produce such a device which shall be simple in construction and efiicient in operation.

To this end the invention consists of certain novel construction and combination of parts, the essential features of which are set forth in the following description and particularly pointed out in the appended claims.

The apparatus is fully illustrated in the accompanying drawing consisting of one sheet, in which 2- Figure 1 is a side elevation of my improved ice-crusher.

Fig. 2 is a perspective view of the crusher block.

Fig. 3 is a detail sectional view of the crusher block.

Like characters of reference refer to like parts in all views. 0

It often happens that the streets of c1t1es become covered with heavy deposits of snow which settles into hard masses or drifts and often become ice before it is possible to remove it. These hardened drifts and masses of ice are a source of great annoyance and present tremendous obstacles to ready removal. The present invention contemplates the providing of means for rapidly breaking up these drifts and masses so they can be easily handled and removed.

Referring more particularly to the drawings, 1 represents a truck or supporting carriage which may be of any suitable construction, but is preferably in the form of an automobile truck. A motor 2 of any suitable type is mounted on the truck and is connected with a winch 3 and with a bevel gear 4. It is of course understood that suitable clutch mechanism is provided between said motor and said winch and between said motor and said bevel gear so that the said motor may operate either or both at the will of the operator.

A post 5 is secured in an upright position on said truck 1 and about the lower end of Specification of Letters Patent.

this is a base member 6 in which a derrick is mounted for horizontal rotation. This derr rick comprises lower and upper members 7 and 8 which are pivotally connected at 9. The member 7 is pivoted in the base 6 and carries attached to its underside, a bevel gear wheel 10 which meshes with the wheel 4. Pivoted at 9 is an auxiliary leg 11 which is normally folded up into the member 8 but which may be let down at will to form an added standard for said derrick.

Mounted in the free end of the member 8 is a pulley 12 and a line or cable 13 from the winch 3 passes over the pulley 14; on post 5, then over said pulley 12, and thence down to the crusher block 15 as shown in Fig. 1.

As shown in Figs. 2 and 3, the block 15 is formed in the shape of a cross comprising four win 16 radiating at right angles with each ot er. Each of these wings is provided on its lower edge with a longitudinal notch or groove 17 in which is seated a shank 18 of a blade portion 19. Bolts 20 secure the blades 19 in place. The cutting edge of the blades 19 is not straight, but as shown, formed with a plurality of scallops or waves 21, which greatly facilitates its cutting action. The front and rear wings 16 are secured to the side wings by angle irons and bolts so that if desired they may be removed; or if desired the front wing may be removed and be replaced by a counter weight to balance the structure.

It is obvious that by throwing the motor into gear with the wheel 4:, the derrick may be turned to or ice deposlts at any side of the truck. When the block is in proper position, the winch is operated bv the motor to raise the block and then permit it to drop. As the block may be made very heavy it will quickly and efliciently break u the ice and snow deposits. When the b ades 19 are dulled or broken they may be quickly and easily removed and replaced.

While I have described what I consider to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way de parting from the spirit of my invention; and I therefore, do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.
